September 18, 2025Sep 18 Hi folks,I've changed USB Flash drives > shutdown and rebooted several times now, and always with the same outcome.Flash drive boots on front USB2.0 portThe system hardware is a Mini Forum MS-A2 AMD 9955hx CPU 128Gb 13Tb Array.Parity drives x 2, Array drives x 13 all connected by USB3.0 hub, tried different hubs withy same outcome.USB hubs are connected to 4 x USB3.0 ports.Memtest on reboot finds no errors.The server has been online and offline for more than a week.The server was operating fine until after 7.1.3 -> 7.1.4 update.What's the best method to downgrade versions? sagittarius-diagnostics-20250918-1811.zip

September 19, 2025Sep 19 Author Thanks Jorge, Posted the lsusb -vt below.FYI this USB connected setup was fully operational for 2 previous Intel NUC server machines with Unraid 6.x and 7.x, and Yottamaster 4-bay external enclosure which uses JMS567 bridge.In any case, I found another 2 posts with similar JMicron bridge issues. https://forums.unraid.net/topic/187956-usb-jbod-drive-mount-issues-after-upgrade-to-70701/ https://forums.unraid.net/topic/170412-unraid-61210-how-to-permanently-add-a-usb-storage-quirk-to-disable-uas/The newest hardware change was the Minisforum MS-A2 machine in late July 2025 without issues until very recently; perhaps the USB driver was also updated recently?Cheers~# lsusb -vt/: Bus 001.Port 001: Dev 001, Class=root_hub, Driver=xhci_hcd/2p, 480MID 1d6b:0002 Linux Foundation 2.0 root hub|__ Port 002: Dev 002, If 0, Class=Hub, Driver=hub/4p, 480MID 05e3:0610 Genesys Logic, Inc.

September 19, 2025Sep 19 Community Expert Click on the flash drive, scroll down to the Syslinux configuration section, make sure Menu View is enabled, top-right, and add after /bzroot to the default boot option, the one in green:usb_storage.quirks=174c:55aa:u,125f:a64a:u,152d:2590:uIt should be added to the same line as /bzroot, just leave a space between that and the kernel option, then reboot and post a new lsusb -vt output to confirm it's no longer using UASP.

September 19, 2025Sep 19 Author Now if I do /dev/sdg (the new assignment) instead of /dev/sdj (the original assignment) then ~# sgdisk -o -a 8 -n 1:1M:0 /dev/sdg***************************************************************Found invalid GPT and valid MBR; converting MBR to GPT formatin memory. ***************************************************************Warning! Secondary partition table overlaps the last partition by33 blocks!You will need to delete this partition or resize it in another utility.Non-GPT disk; not saving changes. Use -g to override.The GUID overlaps by 33 blocks.If i use -g override, I don't think it would change the fact it's no longer being recognised as a Seatay device and the wrong drive issue remains.I guess in that scenario would you agree that I then have to do an array reset with Tools>New Config and select "Preserve current assignments: All" ??

September 19, 2025Sep 19 Community Expert That device will use an MBR partition; you just created a GPT partition on top. The only solution now is probably going to be to rebuild it, assuming parity was valid, but before anything else, post new diags to see the current state.
September 19, 2025Sep 19 Author Ok diags posted thanks Jorgesagittarius-diagnostics-20250918-1811.zip
September 19, 2025Sep 19 Author Let's try that again4 minutes ago, JorgeB said:Those appear to be the same diags as before. sagittarius-diagnostics-20250919-2039.zip
September 19, 2025Sep 19 Community Expert So, if I understand correctly, you ran the partitioning command on /dev/sdg but aborted before doing any changes, so that should still have the original MBR partition, but you also ran the command on /dev/sdj (which is currently disk13)?If this is correct, post the output fromblkid /dev/sdj1
September 20, 2025Sep 20 Community Expert Assuming you didn't reboot yet and disk13 is still /dev/sdj, type:sgdisk -o -a 8 -n 1:32K:0 /dev/sdjThen again, the output fromblkid /dev/sdj1
September 20, 2025Sep 20 Author ~# sgdisk -o -a 8 -n 1:32K:0 /dev/sdjThe operation has completed successfully.root@SAGITTARIUS:~# blkid /dev/sdj1/dev/sdj1: UUID="5bc5fd60-401f-49a2-b8ec-bedab02890f6" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="37e727ec-a367-4c51-a072-9672fff29dbe"
September 20, 2025Sep 20 Community Expert OK, disk13 should now be back to the correct partition layout, and the XFS signature is now there.Parity2 and disk13 got disabled due to USB issues, the disks themselves look OK, so the next step is to confirm if disk13 mounts and contents look correct, type:mkdir /xmount -o ro /dev/sdj1 /xThen browse /x, you can use Midnight Commander, for example, (mc on the console) and see if the contents look OK, if they do, unmount the disk and do the same for disk6umount /xmount -o ro /dev/sdg1 /xNow browse disk6, and if the contents look good for both, unmount disk6 with umount /xand the easiest way to resolve this, would be to do a new config (Tools - New config - Keep all - apply) to accept the new disk6 name and re-enable disk13. You can check "parity is already valid" before array start, but then you should run a correcting parity check.Any issues or doubts, please ask before proceeding.
September 20, 2025Sep 20 Author Solution Ok, thanks Jorge. Disk 13 mounted /x and browsable but no data actualy there as it never completed rebuilding the disk in the array due to the usb uasp driver issue.Disk 6 mounted /x and was browsable with data as expected.I will now execute the new config as suggested.Cheers
September 20, 2025Sep 20 Community Expert 1 hour ago, handycapp said:Disk 13 mounted /x and browsable but no data actualy there as it never completed rebuildingIt should still have the old data, assuming you were rebuilding on top, or was this a new disk?With that disk mounted at /x post the output from du -h -d 1 /x
September 21, 2025Sep 21 Author Interesting development Jorge.The system seemed stable and was rebuilding as expected but overnight the display of Main view is blank and have tested with several devices and browsers, all showing the same thing as per attached screenshot. Other GUI views such as Dashboard, Plugins, Settings etc display as normal, and the Parity rebuilding at the bottom end of Main view (attached) suggests it still running, although system log at time 6:25:40 shows this nginx error:Sep 21 06:25:40 SAGITTARIUS nginx: 2025/09/21 06:25:40 [error] 17238#17238: MEMSTORE:01: force-reaping msg with refcount 1On searching for this error i found this description and possible causes/solutions:The error MEMSTORE:00: force-reaping msg with refcount 1 typically indicates a memory management issue in Unraid, often related to Nginx or the Nchan module.

Check System Logs and ResourcesMonitor system logs (/var/log/nginx/error.log) and resource usage using tools like top or htop to identify bottlenecks.4. Update Unraid and PluginsEnsure you are running the latest version of Unraid and its plugins, as updates often include bug fixes for such issues.5. Reduce System LoadIf high traffic is causing the problem, consider optimizing your configuration or scaling resources.By following these steps, you can address the "force-reaping msg with refcount 1" error and improve system stability.Fix common problems finds nothing of concern.I've attached in-use system drivers' screenshot, Diags, dmesg. log, graphql-api log and system log.Checking the nginx.conf nchan shared memory value -> already set at 256Mhttp { ## # Basic Settings ## # Hide nginx version information. server_tokens off; # Define the MIME types for files. include /etc/nginx/mime.types; default_type application/octet-stream; # Shared memory slab pre-allocated for Nchan. # default is 128M nchan_shared_memory_size 256M; # How long to allow each connection to stay idle; longer values are better # for each individual client, particularly for SSL, but means that worker # connections are tied up longer.

September 21, 2025Sep 21 Community Expert Rebooting should bring the display back, but if it keeps happening, I recommend upgrading to 7.2.0-beta.3, there are some changes that should help with those issues.
September 21, 2025Sep 21 Author Thanks Jorge, @ console nginx stop and start fixes the issue and am monitoring system with Netdata docker to confirm causes.Yes, if it happens again overnight, I'll update from Tools > Update OS after another flash backup and parity disk 2 sync finishes.Very much appreciate the support Jorge😊Cheers
September 22, 2025Sep 22 Author Ok... interesting, it's happened again Jorge.Overnight all drives now with read errors, flash drive unreadable ... diags attached.unsuccessful stop via GUI stop via console -> emcmd cmdStop=Stop -> no indication of array stopping neither from GUI nor console.no option but to powercycle.On rebooting and array start, system seems ok. No read errors, just parity check running ... diags attached.So, the next troubleshooting stage is an upgrade to Unraid 7.2 beta. sagittarius-diagnostics-20250922-1403.zip sagittarius-diagnostics-20250922-1454.zip

September 22, 2025Sep 22 Author Yes, the USB driver and resource limitations are not ideal.Yet, I've had the same setup for years with 2 NUC models and never had these issues before, albeit with 4 fewer drives & no drive enclosure. Currently it's a non-critical backup server, it's worth testing it with the beta and may go back versions until stability is evident.Cheers Jorge.
